Brandywine problems (pics)

[snappybob]

My Brandywine OTV's have been looking pretty good and have now started to put on fruit. I have been noticing the leaves starting to curl in the last week or two and now one of the plants in particular is looking like I may have a problem. I've been spraying every two weeks with daconil and alternating every two weeks with a fish emulsion/seaweed emulsion/molasis spray or drench. I seem to remember something about Brandywines having a leaf curling habit that is normal but this is starting to look abnormal. What do the experts think?

Here is an overall pic.

So what do you guys think. Is it normal leaf curl? Is it a goner? Should I wait and see if the fruit ripens or should I yank it out to save the rest of my plants before it spreads?

Thanks for your help.
